CYCLE-TIRE.

I Specification of Letters Patent.

Patented Nov. '7, 1905.

Application filed September 9,1904. Serial No. 223,819.

To all whom it may concern.-

Be it known that I, ARTHUR S. ALLEN, a citizen of the United States,residing atBrookline, county of Norfolk, State of Massachusetts, haveinvented an Improvement in Cycle- Tires, of which the followingdescription, in connection with the accompanying drawings, is aspecification, like letters on the drawings representing like parts.

This invention has for its object the production of a novel tire for usewith automobiles, bicycles, and the like.

Heretofore many attempts have been made to render bicycle-tirespuncture-proof, and for this purpose wire and sheet metal have been madeinto so-called mail, variously enchained and embedded in theindia-rubber constituting the body of the tire, and when wire was usedthe wire has usually been of such diameter as to add very materially tothe stifiiness of the tire, increasing its weight and lessening itsresiliency.

In my study to provide an improved tire I have produced a flexiblesemimetallic fabric composed of connected wire coils and a fillingmaterial embedded in the interstices of the ,wire, and I have embeddedthis fabric into the body of the india-rubber constituting the tire,vulcanizing the same in position in the body of the tire. The metallicfabric referred to possesses very considerable resiliency and is sodisposed in the body of the tire as to help keep the tire, which ispreferably of the class capable of being inflated, in its working position.

Figure 1 shows a section of a wheel-rim with my novel tire in position.Fig. 2 shows the semimetallic fabric with the wire coils enlarged andwith the filling'applied to the interstices between the coils of wire,and also the locking means, as a cord or wire, uniting the edges of thecoils after the same have intermeshed. Fig. 3 is a plan view of Fig. 2with the filling removed from a part of the wire coils to illustratemore fully how the wire coils are connected.

The rim A, having lips A to be engaged by the hooked edges of the body Bof the tire, and the inner tube 0, which is capable of being inflated,are and may be all as usual.

My improvements relate wholly to the body of the tire and consist inapplying within said body my novel semimetallic flexible fabric, which Iwill now describe.

The fabricD employed by me and embedded in the tire is composed of wire,preferably in the form of coils (Z, laid parallel and having their coilsintermeshed by shoving one coil of wire into the other laterally, thecoils being united by means of locking means, shown as cords or wires(Z, and a filling d of a yielding or plastic material applied to theconnected wire coils to fill the interstices between said wire coils.This filling will preferably contain india-rubber or like material thatwhen applied as described and vulcanized will leave a fabric withsubstantially level sides that may be embedded in the india-rubberconstituting the body of the tire and be incorporated therein by theprocess of vulcanization.

The portion of the semimetallic fabric that is located in the part ofthe tread of the tire, or that part which runs directly upon the ground,may be provided with a filling containing a compound of india-rubber,which when vulcanized will become harder than the other portions of saidfabric running through the inner and outer sides of the tire between thetread-face and the wheel-rim.

Fig. 1 shows the body of the tire as having three layers of wire coilintermeshed and in corporated with the body of the tire. In the centrallayer the fabric is shown as extended substantially about the tire fromone to its opposite edge, while the fabric in the outer layer or treadoverlaps the central layer.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is s i 1. A tire comprising a body of india-rubbercontaining a fabric composed of intermeshed wire coils and locking meansto retain the coils in their intermeshed condition.

2. A tire comprising a body of india-rubber containing a fabric composedof wire coils TOO
